OLAES W. BOMAN, OF NEW YORK, N. Y, ASSIGNOR TO JOSEPH REGKEN- DORFER, OFSAME PLACE.

COMBINED PENCIL-POINT PROTECTOR AND TWINE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 256,629, dated April18, 1882.

Application filed January 23, 1882. (No model.)

To all whom it may concern.-

Be it known that I, OLAES W. BOMAN, of the city, county, and State ofNew York, have invented a certain new and useful Combined Pencil-PointProtector and Twine-Cutter, of which the following is a specification.

My invention is designed witha view to provide what :is usually known asa point-protector or pencil-point protector with an adjunct, by means ofwhich twine and string can readily be cut. An article of this kind is aconvenience generally, but is particularly adapted for use in shops andbusiness estab lishments.

The accompanying drawings represent apoint-protectorembodyingmyinvention. Figure 1 is a side elevation of thedevice. Fig. 2 isa longitudinal central section of the same. Fig. Sis asection on line 3 3, Fig. 2.

A is the point-protectin g tube, which is usually made withalongitudinal slit fora portion of its length at the end in which thepencil is inserted, and is usually provided with aninternally-projecting annular head, I), to limit the extent to which thepencil may be inserted. In the other end of the point-protecting tube isusually inserted a plug of erasive rubber, as shown in the drawings atc. I prolong the tube back of the point at which the bead b is formedsufficiently to permit the introduction into it of acutter withoutinterfering with the pencil'point. The cutter referred to is shown atcl, consisting of a blade with aslauting cutting-edge, d. A convenientway of securing the blade in place is to solder it upright into a cup,6, which is then inserted into the point protecting tube, and afterbeing adjusted to the proper position is soldered, brazed, or otherwisefastened tight in place. At the point where the cutting-edge 61 comesthereis made in the tube a crescent-like slot, f, so formed and shaped,asindicated plainly in the drawings, that the twine to be out, whendrawn down into the slot, will extend across the cutting-edge d, andwill thereby be out. The inclination of the cutting-edge causes thetwine to travel down the edge as it is pulled down into the slot, thusmaking a draw cut.

The device is simple, easily constructed, inexpensive, and entirelyeffective for the purpose for which it is designed.

' What I claim as of my invention is The point-protecting tube providedwith an internal blade, d, and twine-admitting slot or openingf,substantially as hereinhefore shown and described.

In testimony whereof I have hereunto set my hand this 21st day ofJanuary, 1882.
